Color Code Converter
Convert colors between HEX, RGB, HSL, HSV and CSS color names instantly.
What Is the Color Code Converter?
The Color Code Converter is an instant, browser-based tool that translates any color value into every common format used in web development, graphic design, and digital art. Whether you start with a HEX code like #FF5733, an RGB triple like rgb(255, 87, 51), an HSL value, an HSV value, or even a plain CSS color name like tomato, the converter outputs all formats simultaneously — so you never have to manually calculate conversions again.
Supported input and output formats include HEX (3- and 6-digit), RGB, HSL, HSV, normalized RGB (0–1 range used in game engines and shader languages), and the full W3C named CSS color list. A live swatch shows the exact color as you type, and a shade/tint strip lets you explore lighter and darker variants of any color.
How to Use the Tool
Simply type or paste any color value into the input box and press Convert, or use the color picker for a visual selection. Supported input patterns:
- HEX —
#abcor#aabbcc(with or without #) - RGB —
rgb(255, 87, 51)or just255,87,51 - HSL —
hsl(11, 100%, 60%) - HSV/HSB —
hsv(11, 80%, 100%) - CSS Name —
tomato,cornflowerblue,rebeccapurple, etc.
Click any Copy button next to an output to instantly copy that format to your clipboard. Click any shade in the strip to load it as the active color.
Common Use Cases
✦ Front-end developers copying HEX values from design files and needing the HSL equivalent for CSS custom properties. ✦ UI/UX designers checking whether a color has a standard CSS name. ✦ Game developers who need normalized (0–1) RGB values for Unity, Unreal, or GLSL shaders. ✦ Brand designers building consistent palettes by exploring tints and shades. ✦ Students learning about color models and seeing live conversions between formats.
Frequently Asked Questions
What is the difference between HSL and HSV?
Both HSL (Hue, Saturation, Lightness) and HSV (Hue, Saturation, Value/Brightness) represent colors using a cylindrical model. The key difference is how "brightness" is defined. In HSL, a lightness of 100% is always white. In HSV, a value of 100% is the pure, fully-saturated hue — which is how most color pickers in creative software work. HSV is often preferred by designers; HSL is natively supported in CSS.
Why doesn't my color have a CSS name?
Only 148 colors in the CSS specification have official keyword names (e.g., red, coral, rebeccapurple). Any custom mixed color — like #1a7f4b — will not match a named CSS color. The tool shows "No match" in that case, which is completely normal. You can still use the HEX, RGB, or HSL value in your CSS instead.
What does the normalized RGB (0–1) format mean?
Standard RGB uses integer values from 0 to 255. Normalized RGB divides each channel by 255, expressing it as a decimal between 0 and 1. This format is used in OpenGL, WebGL, GLSL shaders, Unity's Color struct, and many other graphics/game engine APIs where floating-point color values are expected.
Can I enter a 3-digit HEX code?
Yes. The tool accepts shorthand HEX like #f60 or f60, which it automatically expands to #FF6600. Each digit is simply doubled: #abc → #aabbcc.
Does this tool work offline?
All color conversion logic runs entirely in your browser using vanilla JavaScript — no server requests are made. After the page has loaded, it works fully offline. Your color data is never sent anywhere.
How accurate are the conversions?
All mathematical conversions (RGB↔HSL, RGB↔HSV, etc.) follow standard formulas used industry-wide. HEX-to-RGB and back are lossless. HSL/HSV conversions may have rounding differences of ±1 in the last decimal due to floating-point arithmetic, but these are visually imperceptible and match the behavior of browser devtools and design applications.
